D-Sub Connectors

DE9SV is the abbreviation for D-subminiature 9-pin shielded with orange shell. It is most commonly used in industrial environments, for computer connections, process control, circuit test and so on. It is one of the most frequently used type of D-subminiature connector.

Application field

The DE9SV connector is well suited for both hand held and permanent installations. Besides, it supports higher signal speeds and resolutions, so it can be used in places with high performance standards, such as broadcasting and telecommunication equipment.

In addition to industrial environment, DE9SV is widely used in equipment like oscilloscopes, video recorders, electric measurement instruments, microwave transmission, satellite transmission and so on. Moreover, DE9SV connector has been employed in entertainment environments like computer gaming, and in medical or scientific fields.

Working Principle

DE9SV connectors features a double-shielded orange colored metal shell, which is suitable for protection of the electrical connection from the surrounding environment. The shields of the DE9SV connector are usually two aluminum shields with stainless steel or plastic insulation in between. The shield can reduce electro-magnetic interference (EMI) and improve its performance.

It employs two rows of staggered pins, with a locking system involving a screw clip on the side of the DE9SV connector, allowing the connector to be locked in place even when experiencing vibration or movement of any kind. In addition to the shields, the pins in the DE9SV are designed to have very precise tolerances, No. 10 size pin having a tolerance of 0.022 millimeters, ensuring solid noise-free connections.

The DE9SV connector supports up to 9 pins in both the male and female versions, with Inherent strain reliefs built into the case of the plug. It also has long established history of use throughout the industrial electrical-engineering industry, due to its rugged, shielded design and its widely available components.
